Bump on the Bridge of my Nose 10 Months After Rhinoplasty?

At this point, I suspect the bump will not resolve on its own. Ask your doctor about steroid injections to lessen the bump, as it's most likely scar tissue. I suggest waiting a bit longer before considering a revision, as the tip may get better definition. 

That is a long time out to have a residual bump. The things you describe are things you should have your initial surgeon or a second opinion surgeon look at. I always feel that a patient should give their original surgeon the chance to make things right if you are concerned about certain issues. I won't revise a nose for about one year in 99% of situations, but sometimes you can go back sooner for minor alterations. Understand that you may still have to pay for an anesthesia and facility fee if you need more surgery. It will be up to you and your surgeon how to handle other fees. It is so important that you understand this because may patients expect it will not cost to proceed with additional changes and more than not it does. So these need to be changes you want really badly. In some situations things can be done in the office if they are minor.
